I would recommend a dictionary for your map system, as that is what is primarily used. And if you want to use an array, use reserve.
but here, have a nice little thing I'm coding as i type this post.
This is mainly useful for 2dp games, but it'll work, and the less map data you need the less memory it eats.

dictionary map;
void set_tiles(int minx, int maxx, int miny, int maxy, string type)
{
for(int x=minx; x<=maxx; x++)
{
for(int y=miny; y<=maxy; y++)
{
map.set(x+":"+y,type);
}
}
}
//now, say I wanted to get the tile. Let's have a nice little string function for that. If it's air, return blank so it's air, unless you have a tile for air... Laggy!
string get_tile_at(int x, int y)
{
if(map.exists(x+":"+y)==false) return '";
string temptile;
map.get(x+":"+y,temptile);
return temptile;
}
//and now, if you wanted to get the players tile, assuming playerx and playery are your vars, you could write a function like this.
string get_player_tile()
{
return get_tile_at(playerx,playery);
}

I would highly recommend a dictionary over an array for map tiles and such.

BGT dictionaries are kinda cumbersome. I'd write get functions to simplify retrieving data from them, for example:

string gets(dictionary@ d, string key) {
    if(@d==null or d.exists(key)==false) return "";
   string ret="";
    d.get(key, ret);
    return ret;
}

You'd need to do the same for other types, though, unless there's a way to return an unspecified type in BGT, and I just haven't come across it.

I'm not sure I understand the original question well enough to know if the dictionary advice is the best solution. I think I get what you're asking--code can get clunky and unwieldy and hard to remove from its original context--but I'm not sure I understand what the example is trying to do well enough to offer improvements.

Hi!
Can you give me an example Side Scroller games, which of the following you can:
Click on the right's start.
To start off an intro, which can carry hereinafter press Enter.
The main menu is a hit, and when he comes in, a menu music tone, and when the music's over, start again.
The menu is a new game, a reload a saved game, a speaker test, and leaving menu items are.
The exit when you press enter, leave, and come in a test speaker sound in a left to right, which indicates that both speakers work.
By clicking on the saved game to reload immediately start the game right where I left off previously.
The new game when you click, you can start up a music that goes on during the game, and the menu will stop the music, instead of the game do you speak music.
Right, left able to go to the beginning of the track shall be left wall, the wall can be left at the end of the track, and that's no matter how long the track.
So you can go right to the left, to be run control to right and left arrow keys, and jump with the up arrow button, no matter how big jump, but it is also possible to press the up or right arrow, what causes it up and to right to jump all position number.
Shoot be a space or a singer can be used with a sword, two singer be able to use the knife, three coat rack is the bomb.
Pressing the key EF4 know to save my game, and the Escapee be the main menu again, but first ask if you want to make sure that this move?
Press Enter to quit the Escapee and rewind the game.
If you ask, the whole sound_poollal be solved. That's it.
Sorry, my English is still a bit flawed, since I am Hungarian.
Thanks in advance.

Hi,
have you tried to use a service such as Google Translate to write your post, or have you put it together off the top of your head?
In any case, whatever you did, it might be good to try the other way round, so if you translated this post with a software, try to word it yourself, or if you did just that, try to have it translated for you instead.
Like this, your post unfortunately makes no sense at all.
Hope this helps,
Lukas
